For all the tech heads out there, I'm hoping you can give me some help.

All of a sudden, my Xbox can't connect to Live any more. I ran the tests and it can get internet, but the bar stops about 1/3 the way to LIVE. And everytime I did the test connection on the Xbox, my router would reset, disconnecting everything for a brief second or two. For the record, my PS3 connects to PSN just fine and my laptop works fine when wired. Any ideas?

I've been connecting to Xbox Live thru a bridge connection thru my laptop, but I often can't get into the same games as my friends. It feels limited I suppose.
